T0 all whom may coiieem.'

Be it knownl that I'. @Amin A. Benin', a

he a vlull, clear, and exact description ol the invention, such will enahle others ekiiled,

inthe artto which it appertains to make and use the reference heine' had to the accompanying drawings, und to the tigures et reierenee marked thereon.y which form a part ot' this specification.

This invention rehites to oeil rovere; tor Storage batteries and one ot' the ohjerts thereof is to provide :i eornhined sell cover, filler tuhe, gas relief meansl and leeparator guard for storage batteries, which maj," he inexpensively 'eonstrueteth conveniently applied and which will poeeess eertein inherent advantages over known types oi storage battery Cell covers.

rlhe invention consiste in certain novel detailsmt eondtruetion and 'arrangements ei" parte, all ot which will he speed alliI described hereinaftera reference heinehuld to the accompanying; drawings, in which Fig. 1 is a vertical. longitudinal, Sectional View through the upper portion of zi Storage battery cell to which my inventioii is ap plied Fig. 2 is e detail perspective view ot the Cell cover, and

Fig. 3 is a cross sectional view thrmigh the (zeil showing the filler tuhe plug removed.

The reference numeralA 1i. designates :L Stor-:ige huttery box adapted to Contain e plurality ot oeils and hold them in position hy :L grii'l Cell trame 2. 8 desigi ate@ a storage hatt/ery eell jar of insulating miiterial, 'tor ixanuole ruhhei; in which are arranged in the usuel wav the' positive plates {.1. andthe negative plates with separators between them.

The positive platee l have their te i ninale Connected to a` Strap 6. which Supportl a poet- 7. rThe vneffdtive. platee 5 are eonnertedA to a Strap which supporte a negative post i). The Straps are spared apart lo provide :t space i() and the posts 7 and f) may he eonneeted to compienientary posts hy hues har l'i and 12.

Theronstruetion thus tar de. frihed is the conventional type ot' storage battery, it he- Specifieaton of Letters .Ee-tent i. atente@ 55.35, i922@ serial. No. .555',eee.

ingr uuderstomi, of course, that there is eleetrolyte in the oeils. y

My invention eontenuiihitee e Celi oever of' novel eouetruetion, The Cell. rover )rovided with en inverted. trougheheped, transversely disposed niernher 11.3, open et the hottoin7 to provide Chambers isian'd 15., the hottoin edges-1 or' which rest upon the straps (3 :1nd 8 and hetween the, straps 5 and H are depending- Hangt-,s or side weile ind 1'?, whirh extend troni the top itl of the rover to the top edges of the plates et and .f7 and as they extend across the platee land their hottom edges ronstitute separator guarde, that the" serve to prevent the separatorsl troni floating in the electrolyte and therehy hold them in their proper tze-operative positione with respect' to the plateel l alud 5.

The eide -walls i6 and l? constitute the eide walls: ol a gas relieving ehemher 20, having zi floor wall 2l` in which is a threaded collar 22, th(l opening' ol' which aiigns with the filler opening :'23 in the top '18. The Side wails iti and i7 ere provided with gas escape ports 24 and 24 whei'ehythe gas l'orn'ued in thil ell may paies through the ports 24 and El into the uhamher 20 epd escape throughLthe'inclined porte 25 in lthe liller tuhe plug). The filler tuhe ping; has e linuried head 2T at its upper eno provided 'with :i thingie or follar 28 adapted to ref-:t upon it gasket 55S) supported hy the top i8 and surroiuuliugj the filler opening f2.3.

The lower end oi the plug 2G is thredeth as at EN), to engage the threads of the collar 22 so that surrinavllv the ilier tube opening' wiil he closed when the plug` is screwed into the roilar so that the ih; 2H hears upon (he ,f raeket or washer it vill he ohe'erviul hv reference to Fig. that when the plug` if# in ite eioeing peeition. tlu` oulfie ol' the i irte 25 are open to atriuplwrr so that the fue generated in the (-l-ll inav pase through the portel und 5M into liuxl :zhzuuher ifo and out to :itn'aophere ljhrou h he ports Vihen ii'Y fill or repienish hattery. the plug;v is r.ir-'errwed from (follar and :dure this openinggolthe 22 is in line with th' liller ruhe openii it i# ohvioue' that liquid may' he introi' into the hattery fell through 'the :aligning ogiruinggs without removing; the rover.

The Cover rests upon the straps; 6 :me and it is provided with poet opening@ t i desired to th l 32, through which the posts 7 and E) may project to be connected to the buss bars 1t and l2.

By reference to the drawings, it will be apparent that the combined eell cover, filler tube, gas relieving device and separator positioner may be constructed ot two pieces, the cover proper with its integral appurtenances and the removable plug 2o.

'hen the cover is in place and the buss bars are secured to the terminal posts T and 9, liability ot' the cover having relative play with respect to the rest ot'y the battery will be prevented and lsince the cover is provided with a peripheral liange l which eX- tends around its lower edge to rest upon the straps t3 and S and since the grid trame 2 will rest upon the upper l'aee ot the t'lange. it will be apparent that liability ot the cover having movement will be eliminated.

Iif actual practice when the cover is in the, position shown in Fig. l and it is desired to till or replenish the battery or introduce the electrolyte into the cell, it will be only neces-l sary to take out the plu y 2() and introduce the liquid. Then the plug can be secured in place and the battery will be ready Vl'or use.

The. tioor portion 2l not only serves as a support for the collar to hold the plug in place lult it also acts as a splash guard so that liability ot: the electrolyte splashing out ot' the battery will be entirely eliminated.

Indeed, there will be very little liability ol' the electrolyte being splashed out olI the cell but in the event that it should splash into the chamber 2t), it will immediately run bat-lo into the cell through the openings 24 and Z-i. lt cannot splash out ofthe cell because the plug seals the cover through the rncdium'ot the gasket 29. 'l`heretore, liability7 ot: thc electrolyte splashing around the terminal posts T and tl so as to cause corrosion or to eat away the connections between the buss bars and the posts will hc entirely avoided.

(.)bviously the device can be readily applied on existing batteries in a most convenient manner and it may be easily constriufted and inexpensive to n'ianutacture.
